Beit known that I, RICHARD MoBLEY, a citizen Yof the United States, andy a resident of the city of St. Louis, Missouri, `have inl' 5.. vented certain new and useful Improvements in Car-Doors, of which the following is a specification containing a full, clear, and

exact description, reference being had to thel zo tion of a portion of the side of a ,box-ear,v showing thedoor seated in the door-opening and lockedin place therein. Fig: 2 isv atop view of the track whereonthe door is hung. Fig. 3 is aV transverse verticalsectional view z5 of the top and bottom. ofthe door, taken- Fig. 4 is a transalong the line 3 3 in Fig. 1. verse vertical sectional view of the same, taken along the line 4 4 in Fig. 1. `In both Figs. 3 and 4 the middle portionof the door` 3o is shown as being broken away. Fig.- 5 is an enlarged view in perspective of the 'locking device applied fin the door of my invention. Fig. 6 is an enlarged perspective view of the hanger 9. Fig. 7 isan enlarged perspective 35' view of the portion of the mechanism whereby the hanger 9 isactuated. Fig 8 isla transverse horizontal sectional View of the portion of the lockingmechanism, taken along thelineSSin Fig. 5. i f 4o The door 10 is suspended from the track 11, which runs parallel with the side wall of the car, and at or near the 'forward' edge of thev door-opening 12 the trackrecedes, as shown in Fig. 2, so as to force the forward edge of 45 the door into its opening when the door is closed. Supporting-rollers- 13 and 14 are carried by the hangers 9 and 15, respectively. The hanger 15 is rigidly mounted upon the door 10, as shown in the front view in Fig. 1 5o and in sections in Fig. 3. The form of the hanger 15gis illustrated in the figures referred to, and it is provided with a sleeve 16, around Which-the roller 1 4 is mounted, the roller 14 v specification of Letters Patent.

being secured in place by the rivet 17 retaining-washer 17a. At the lower 55 edge of the door-opening 12 I havejproded' the bracket member 18, which serves ttihold thelower'forward edge of the door 1( 1xin' place when the opening 12. o'

In order to rovide means for thrusting the rear edge o lthe door intoposition within the ydoor-opening 12, yI have 'mounted the` roller 13 upon a tilting hanger 9, which hanger .l

door is seated in thedoor,

9 is provided with a stud 18?, upon whichthe 5"5 roller is mounted, said roller'l beingheld place by means of the rivet 19 and retainingwasher19" I i .l

The hanger 9 hasl itslower portionfpivotl ally connected to"a base-plate 20," having perforated lugs'2`1, whereby .the base-plate is secured to the rear upper edgel of the door '10. At its lower end the` base-plate 20 I is provided with the perforated projection 22,

upon which the hanger 9 is pivotally mountf j 5 y.

ed by means of the pin 23". Atl its upper l. end the base-plate 20 isycc'mnectedl tothe hanger 9 by means of a toggle-lever comprising the link 23, pivotally connected to the plate 2O by means ofthe pin 24,'and a link 25, So pivotally'connected to the hanger 9 bymeans of a pin 27, said two links `beingpivotally l connected together and toa bar 2 5av fb means of a pin 26. The innerend of the lin v25is preferably slotted, as indicated 4by the 85 numeral 28, to receive the upper end of the vertical rod, which is held in place within the slot 28 by means of the pin 26.` The vertical rod 29, intermediate of its ends,l passes vloosely through the guide 30, mountedjupon, 901

the outer face of the door 10. 'j

At its lower end the vertical rod 29'i`s connected with and actuated by the lever 31 to which it is pivotally` connectedby means of the pin 33.

the pin`3f1Y and has its lower end wedge# shaped and provided with an opening 35`to receive the locking member 36. VAsishown in Fig. 8, the locking member 36 is pivotally Loo 'I mounted within the opening 35 b"} f'rne`ans ofl of the doorfope'ning 12 andis provided with m5 The lever 31 is pivotally mount- 955 i' -ed within the guide member 33 by means `of The locking member 36 is provided with a downward extension 4 1, having the opening 42, the opening 42 being so locked as to be substantially in alinement with -the openings when the locking member 36 Vis in its locked position. The locking of the door is then eected by means of running .the band or wire 43 through the openings 40 and 42 and securinfy the ends of said band or wire 43 by means of the seal 44'.

ln lts closed position the door 1() is seated in place within the. dooicpening 12, as shown being thrown inwardly by reason of the tog-- 'I5 in section in Fig. 4, the rear edge cf the door gle-links 23 and 25 being thrust into'substa'n` tial lalinement by the upward thrust of the vertical rod 29. The hanger 9 is provided with an inwardly-projecting lug 45, whereby thed upward movement of the link 25 is lime 1te .l

When it is desired to open the door, the seal is broken and the lower end of the lever 31 is swung out of ergagement with its bracket-lug, causing aY downward pull upon the vertical -rcd 29. By means of this pull the rear edge of the door is moved ont ofits 1 seat when the door may be slid out of its position. in front of the door-opening 12.

It will be observed that in operating the door. the receding portion of the 4track will force the Ifrontedge of the door into its opening, and when the lever 3l is swung to engage its bracket-lug lit will move downwardly, such motion forcing the rc d 29 upwardly ar. d moving the toggle-links to positions wherein.

y pivotal centers are alired. In this position the toggle-levers are subjected only to end thrust, and thusthere'is no strain placed on nthe rod 29. The memheris in the form of a. hook, which drops over the bracket-lug'arl tends to prevent accidental ,displacement .4 thereof. Gravity also assists in holding the p .lever 31 in engagement with the bracket-lug.

When the pivoted member 36 is sealed, it is dObvious that the sealing-wire will be `drawn sufficiently tightly to prevent this hockshaped member from having its nose lifted above the bracket-lug, and consequently7 the lever 31, cannot be swung on its pivot. l' Then the door is opened, the hooked member 36 must be disengaged from the bracket-lug and the lever 31 swung so that its free end, which carries the hooked member 36, will be lifted.

This depresses the rcd 29, collapses the toggle-links, and moves the rear edge of the door outwardly past the side wall of the car, perl mitting ,the door tobe slid cn its supportingtrack away from the door-opening. When the door is open, the operator of course releases the lever 31 .and the weighted free end ofthe lever will drop by gravity, forcing the rod 29 upwardly, .and consequently permit'.- ting they :rear'edge of the door to move inwardly against the side wall of the car. This I consider an important feature of my inveni tion, because when the door is opened the` tendency of the locking-fixtures is to hold the door firmly against the side wall of the car, and so prevent ymovement. of the door is claimed as new, and desired to be secured by Letters Patent, is-
